CUI Fundamentals White Paper
Corrosion Under Insulation (CUI) is a major issue for oil, gas and chemical process industries. It is estimated that up to 10% of annual maintenance costs are caused by CUI; severe cases of CUI may put personnel, environment and reputation at risk. Furthermore it’s estimated it accounts for 40% to 60% of pipe maintenance costs – estimated to be around $1 trillion annually.
We’re here to help: our lightweight, resilient and compact insulation systems provide highly effective barriers to water and water vapour.
A holistic approach to insulation systems designs reduces the risk of CUI.
The potential influence of thermal and acoustic insulation materials is normally assessed through a series of individual laboratory tests on the insulation materials themselves, but very rarely on the applied system.
A more sophisticated holistic approach takes into account not only the applied insulation system, but also the CUI failure behaviour.
Through using this approach we hope you are able to better identify vulnerable areas on a facility allowing for appropriate CUI strategies to be implemented.
